Does PVC Pipe Have Long Life Expectancy?
Yes, studies on PVC pipe made in Europe in the 1930s and been in continuous use suggest a very long useful life for these products of a hundred years or more, which will generally exceed the lifespan of the structures they are installed in.
Furthermore, PVC has an impressive record of long-term durability. When water utility managers and engineering firms were surveyed in a study sponsored by the American Water Works Association Research Foundation, they cited corrosion resistance, longevity and durability as their top reasons for choosing PVC. When these same water supply professionals were asked to rank PVC against the other common types of pressure pipes for life expectancy, PVC ranked first.

Uni-Bell has an extensive collection of technical papers and experience articles that cover the subject of water and sewer pipe longevity in detail. These items are available, free of charge, by contacting Uni-Bell. (http://www.uni-bell.org). They point to the same conclusion that 100 years is an extremely conservative estimate for the service life of a properly designed and installed PVC pipe.
